See document of YMGA_CBTable Table: Selection list with multiple columns.
The user can select exactly one row (with all its columns) from that list. Each cell (each column within each row) has a label text and an optional icon (*).
This widget is similar to SelectionBox, but it has several columns for each item (each row). If just one column is desired, consider using SelectionBox instead.
Note: This is not something like a spread sheet, and it doesn't pretend or want to be. Actions are performed on rows, not on individual cells (columns within one row).
(*) Not all UIs (in particular not text-based UIs) support displaying icons, so an icon should never be an exclusive means to display any kind of information.

Constructor.
'header' describes the table's headers: Number of columns, column headings, and column alignment. The widget assumes ownership of this object and will delete it when appropriate. The header cannot be changed after creating the widget.
'mode' indicates whether the checkbox is in the first or in the last column.
header must contains also header for checkbox column (empty string is allowed if not wanted)

Add one item.
This widget assumes ownership of the item object and will delete it in its destructor.
NOTE: For tree items, call this only for the toplevel items; all non-toplevel items are already owned by their respective parent items. Adding them to the parent widget will clash with this ownership.
Reimplementation of YSelectionWidget::addItem.

Notification that a cell (its text and/or its icon) was changed from the outside.
Applications are required to call this whenever a table cell is changed after adding the corresponding table item (the row) to the table widget.
Derived classes are required to implement this and update the display accordingly.
Note that the position of this cell can be retrieved with cell->column() and cell->itemIndex().
|
virtual |
Return the item which value is changed (e.g.
checkbox).
Definition at line 75 of file YMGA_CBTable.cc.

pure virtual |
check/uncheck Item from application.
Derived classes are required to implement this and update the display accordingly.
Note that item->check(true) does not update the table
|
virtual |
Get a property.
Reimplemented from YWidget.
This method may throw YUIPropertyExceptions.
Definition at line 256 of file YMGA_CBTable.cc.
bool YMGA_CBTable::hasColumn | ( | int | column | ) | const |
Return 'true' if this table has a column no.
'column' (counting from 0 on).
Definition at line 117 of file YMGA_CBTable.cc.
bool YMGA_CBTable::immediateMode | ( | ) | const |
Deliver even more events than with notify() set.
With "notify" alone, a table widget sends an ActivatedEvent when the user double-clicks an item or presses the "space" key on it. It does not send an event when the user just sends another item.
With "immediate", it also sends a SelectionChangedEvent when the user selects another item. "immediate" implicitly includes "notify".
Definition at line 135 of file YMGA_CBTable.cc.
bool YMGA_CBTable::keepSorting | ( | ) | const |
Return 'true' if the sort order is to be kept in item insertion order, i.e.
if sorting the table by clicking on a column header should be disabled.
Definition at line 150 of file YMGA_CBTable.cc.
|
virtual |
Return this class's property set.
This also initializes the property upon the first call.
Reimplemented from YWidget.

virtual |
When derived classes emit YWidgetEvent with reason ValueChanged they have to set which item is changed.
Who manages the event have to use changedItem() to get it.
Derived classes can overwrite this function, but they should call this base class function in the new implementation.

virtual |
Switch between sorting by item insertion order (keepSorting: true) or allowing the user to sort by an arbitrary column (by clicking on the column header).
Derived classes can overwrite this function, but they should call this base class function in the new implementation.

Set a property.
Reimplemented from YWidget.
This function may throw YUIPropertyExceptions.
This function returns 'true' if the value was successfully set and 'false' if that value requires special handling (not in error cases: those are covered by exceptions).
Definition at line 229 of file YMGA_CBTable.cc.
void YMGA_CBTable::setTableHeader | ( | YTableHeader * | newHeader | ) |
Exchange the previous table header with a new one.
This will delete the old YTableHeader object.
If the new header has a different number of columns than the old one, all items will implicitly be deleted.
Definition at line 99 of file YMGA_CBTable.cc.
YCBTableMode YMGA_CBTable::tableMode | ( | ) |
returns the YCBTable checkbox position mode

YCBTableItem * YMGA_CBTable::toCBYTableItem | ( | YItem * | item | ) |
useful cast for bindings.
it just performs a dynamic_cast

The name of the widget property that will return user input.
Inherited from YWidget.
Definition at line 272 of file YMGA_CBTable.h.
YItem * YMGA_CBTable::YItemIteratorToYItem | ( | YItemIterator | iter | ) |
useful cast for bindings.
it does not any assunption on iter, so it is up to the user to check if it is valid, it just returns *it.
